STUDY DESIGNBlinded randomized controlled trial.INTRODUCTIONIt is generally accepted that heat is beneficial for improving range of motion (ROM). However, the mechanism of action is not clearly understood, and the optimal method of heat application has not been established.PURPOSE OF THE STUDYTo investigate the immediate effects of using a moist hot pack (MHP) vs therapeutic whirlpool bath (WB) for improving wrist ROM during a therapy session for patients with distal radius fracture.METHODSAbout 60 adult patients, with a mean age of 54 years in the MHP group and 53 years in the WB group, with healed distal radius fracture were randomized into 2 groups of 30. Patients in group 1 were placed in an MHP for 15 minutes during therapy. Patients in group 2 had their arm placed in a WB and were asked to perform active wrist ROM exercises for the same period. This occurred for 3 consecutive therapy visits, with wrist and forearm ROM being measured before and after heat during each visit.RESULTSThe multivariate analysis of variance demonstrated that the canonical variate for ROM was significantly different between groups (F[6,53] = 6.01; P < .05), indicating that patients in the WB group had a significantly larger increase in ROM than patients receiving MHP application.DISCUSSIONBoth WB and MHP improved wrist ROM during therapy sessions in this study, making both these acceptable options for clinical use when the goal is to precondition a patient for other treatments.CONCLUSIONSIndividuals who received WB showed a statistically greater increase in wrist ROM than those receiving MHP during a
